- Connect with Texas Instrument's SensorTag Device over BLE (Bluetooth Low Energy)
- Auto-reconnect mechanism as BLE exception occurs frequently

There shouldn't be the requirement of get_sensor_tag(), just have one definition for sensor tag device and use it.

There shouldn't be a separate class for collecting metrics, make it part of SensorTagDevice class. Creates confusion and complexity for user.

Why is SensorTagDevice dependent on SensorTag ? Any specific requirement, I`m not clear with this implementation.

This line should be part of user code(Initializing Device class) shouldn't be in the core Liota.

Create a separate device package and metrics package. Initialization of device shouldn't be part of this device metrics package.

Just keep the device metrics in this package, don`t combine the device metrics and edge system metrics in the same package.

Just keep the package dependent on the device metrics only.

Just rename the path as "packages/examples/metrics".As you are making the new folder I`ll prefer if you can move the entities in the specific folder.

Okay will rename it. For packages, we need to move device and metric entities separately. This will result changes in many files. In the interest of keeping no.of files changed for a PR less, I'll raise a separate one just for refactoring once this is merged.

Can the interval be other than "0"?

We provide sampling interval here
So, to collect from SensorTag, it must be zero.

We have separate folder for model_simulated examples. This is the first actual device. DHT examples can go in here.

Probably you can move all the metrics associated package in this folder.
